CLO GK- SYN CHRON IZER.

Specification of Letters Patent.

Patented July 14, 1914.

Application filed October 23, 1913. Serial N 0. 796,864.

To all whom it may concern:

Be it known that LMAX HENDLER, a sub ject of the Czar of Russia, residing at the city of Staunton, State of Illinois, have invented a certain new and useful Improvement in Clock-Synchronizers, of which the following is a full, clear, and exact description, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, forming part of this specification, in which the illustration is a v perspective view showing my invention and .its application to the clock-casing.

The object of my invention is to provide a simple and easily operated mechanism for synchronizing the striking mechanism of clocks with the time indicating mechanism.

As is well known, it frequently occurs that clocks are allowed to run down and are reset by inexperienced persons before they are wound. It sometimes occurs also that the striking mechanism is not wound and runs down before the time mechanism does. These occurrences will cause the relation oi the striking mechanism and the time indicating mechanism to be altered so that the clock will not strike the time indicated on the dial. Persons unfamiliar with the clock mechanism are at a loss to remedy this state of affairs and either allow the clock to go on striking out of time or in seeking to correct it, put the clock out of order. By means of the mechanism illustrated in the drawing, the inexpert person is enabled to synchronize the striking mechanism with the tlme mechanism by simply pressing a button in the casing of the clock and the addit on of this feature renders the clock more desirable in the eyes of the ordinary purchaser, and, therefore, renders it more salable. By means of the form of device employed, I am enabled to position the operating element near the base of the clock casing where 1t may be easily reached and yet is lnconspicuous.

As illustrated in the drawings, 1 1s the clock casing, and 2 a portion of the frame. Let 4 represent the striking wheel and 5 the striking wheel escapement detent. The counting wheel is indicated at 6 and the counting detent at 7. These are all well known portions of a clock str1k1ng mechanism and operate in the usual fashion, the detents 5 and 7 being both fixedly mounted on the shaft 8 and operating to control the rotation of the striking wheel 4. As is usual in clock striking mechanisms, the counting wheel 6 is provided with peripheral notches 6 which are divided into groups by the measuring notches 6 iVhen the controlling detent 7 drops into one of the measuring notches 6 the detent 5 will be permitted to engage suitable means on thestriking wheel 4 to prevent further rotation thereof and further striking. lVhen the detent 7 is lifted out of one of the measuring notches 6 the striking and counting wheels are released to rotate, the detent 7 engaging sucoessively the peripheral notches 6*, and during this rotation, the striking of the clock continues. As a means for thus lifting the detents 7 so as to free the striking mechanism and permit it to assume the proper position relative to the time indicating mechanism, I provide the lifting link 9 which is slidably supported on a portion of the clock frame 2. This lifting link has an ear 9 which projects under the detent 7 in position to engage the same and lift it out of any of the measuring notches 6 when the lifting link 9 is raised. A suitable spring 10 retains lifting link 9 normally in lowered position where it does not interfere with the operation of the detent 7. Mounted in the clock casing is a push button 11 which may be moved inwardly against the influence of the extension spring 12. Push button 11 carries a cam 1A which engages the lifting link 9 in such fashion that when the button 11 is pushed inwardly, the cam.

14: raises the lifting link 9 so that it will engage the detent 7 to release the striking mechanism. The button 11 is seated in a proper seat 15 supported in the casing at a point preferably near the base of the clock where the button may be easily reached when the clock is positioned on a high suport.

p The operation of the device will be obvious from the foregoing description, from which it will be apparent that this device provides a simple and easily operated attachment for synchronizing the striking mechanism of a clock with the time indicating mechanism.

\Nhat I claim is:

1. In a clock including a striking mechanism and controlling detents therefor, a means for operating the detents comprising in combination a vertically movable lifting link cooperating at its upper end with said detents, a cam member cooperating with said lifting link at its lower end,.anda push button disposed in the lower portion of the clock casing and adapted to operate said cam member for the purpose described.

2. In a clock havinga striking mechanism adapted to cooperate with said lateral extension .to slide the link upwardly, and
